Form RT3116 12-18

This form certifies that the overhead line equipment (OLE) including return conductors, booster transformers and autotransformer feeders, are electrically isolated where necessary and earthed, and constitutes a Permit-to-Work on or near these

The form has been revised to improve usability.

At TOM SC on 3 September 2024, the committee approved withdrawal of four forms (RT3112, 3113, 3114, and 3116). These forms are maintained by Network Rail’s technical authority and now incorporated into NR internal standards NR/L3/ELP/29987.
